Frost protection of the high-pressure pump ATTENTION Frost Destruction of the device through freezing water Completely drain the water from the high-pressure pump and water system. Store the device in a frost-free location. If frost-free storage is not possible: 1. Rinse the device with anti-freeze as described be- low. Note Use commonly available, Glycol-based vehicle antifreeze. Observe the handling instructions of the antifreeze manufacturer. Anti-freeze flushing - advanced version 1. Shut off the water inlet 2. Start the device and operate it with the high-pres- sure gun open until the float tank is empty. 3. Interrupt the operation. 4. Pour approximately 5 litres of anti-freeze into the float tank. 5. Start the device. 6. Open the high-pressure gun. 7. If anti-freeze leaks from the nozzle, close the high- pressure gun. 8. Keep the device running to flush the bypass system. 9. Open the pump ventilation lever until anti-freeze comes out of the ventilation hose. 10. Switch off the device. 11. Disconnect the spray unit (high-pressure hose and high-pressure gun) from the device. Anti-freeze flushing - classic version 1. Use an external pump to feed anti-freeze into the device at the water connection. 2. Wait until anti-freeze flows out of the bypass pipe of the high-pressure gun. 3. Open the pump ventilation lever until anti-freeze comes out of the ventilation hose. 4. Finish feeding in the anti-freeze. 5. Disconnect the spray unit (high-pressure hose and high-pressure gun) from the device. Frost protection of the combustion engine 1. Check the engine coolant filling level. 2. Check the antifreeze range of the engine coolant. Storage If the device is being stored for 6 months or longer, the following measures must also be carried out. 1. Carry out the maintenance procedure that is due next. 2. Flush the radiator and fill it with long life coolant. 3. Remove any traces of oil and grease from the out- side of the engine. 4. Either completely empty the fuel tank or fill it com- pletely. 5. Lubricate the engine speed lever. 6. Disconnect the battery cable from the positive termi- nal of the battery. 7. Check the battery acid level and top it up with dis- tilled water if necessary. 8. Protect the device against the ingress of water and dust. 9. Charge the battery on a monthly basis during stor- age. 10. Let the engine tick over every 4 to 6 months without starting it. Restarting after storage 1. Check the engine (see "Initial startup"). 2. Establish the water connection for the high-pressure pump. 3. Vent the low pressure system of the high-pressure pump. 4. To supply the engine with oil: a Let the engine tick over for 15 seconds without adding any fuel. b Wait 30 seconds. c Carry out this procedure a total of 4 times. 5. Fill with fuel. 6. Start the engine. 7. Operate the engine at idle speed for 15 minutes. When doing this, check for fuel, coolant and oil leaks. 8. Observe the control displays to ensure they are working correctly. 9. Check the oil pressure. 10. Avoid prolonged periods of idle or maximum speed for the time remaining of the first operating hour. Care and maintenance ƽ DANGER The device can start unintentionally. The high-pressure water jet or impelled parts can cause injuries. Before starting any maintenance work, set the key-operated switch to "0" and actuate the trigger of the highpressure gun until the device is depressurised. Remove the key from the key-operated switch. Danger of burns The engine, especially the muffler, gets hot during operation. Touching hot parts of the engine can result in burns. Do not start any maintenance work until the engine has cooled down sufficiently. Risk of scalding Hot engine coolant and steam can escape when the radiator cap is opened and cause severe scalding injuries. Do not open the radiator cap until the engine has cooled down. Tighten the radiator cap firmly. ATTENTION Risk of damage Water ingress will damage the engine. Protect the air filter and electrical components before cleaning the engine with water or steam. Risk of damage Incorrect cleaning processes will damage the engine. Do not use a wire brush to clean the engine. Do not clean the engine with a water jet exceeding 1.9 bar. Note Old oil may only be disposed of at designated collection points. Please dispose of any old oil at these locations. Polluting the environment with old oil is punishable by law. Safety inspection/maintenance contract You can agree on regular safety inspections or close a maintenance contract with your dealer. Please seek advice on this. Maintenance intervals Each time before use 1. Carry out the following checks on the engine every day prior to start-up. a Check for oil leaks. b Check for fuel leaks. c Check for coolant leaks. d Check for damage or missing components. e Check for loose, missing, or damaged connecting elements. f Check the wiring for cracks, abrasion, and damaged or corroded connections. g Check the hoses for cracks, abrasion, and damaged, loose, or corroded holders. h Check the radiator for contamination and, if necessary, clean the cooling fins with compressed air (maximum 0.19 MPa). i Check the water separator for water and contamination; drain the water separator if necessary (see "Maintenance work"). j Check the engine oil level (see "Maintenance work"). k Check the coolant level (see "Maintenance work"). 2.
